On Panasonic Lumix DMC-LX100 First Impressions Review preview (1869 comments in total)

Seems like a lovely pocket camera. Something to finally trump the Sony RX100 series.
However the "multi-aspect" cropping modes is just stupid. How about using the entire sensor and letting us choose how to crop it ourself? Tossing out 25% of the pixels (or more) by doing what anyone with any photo editing software can do better on their own?
It doesn't change the fact that this is the camera with the largest sensor in class (ignoring the APS-C bulky things). But all anyone who wants to trump this camera has to do is make a clone of it without these modes and they can legitimately claim to have a 25% effective larger sensor and a higher resolution as well.
Dumbest feature ever.

On Tamron SP 150-600mm F/5-6.3 Di VC USD Lab Test Review preview (231 comments in total)
In reply to:

Rob van Zadelhoff: If they have already sold some 400-500 of this lens, why would a large camera store in NYC not be able to deliver? When will this lens be widely available?

The issue is just demand. Everybody seems to want one.
I called a couple of shops (local to Seattle) and they had all sold everyone they were allocated and typically had a 50+ person waiting list.
Amazon said the same thing (although less specific). They have a 1-2 month waiting list.

On Nikon announces AF-S Nikkor 20mm f/1.8G ED article (73 comments in total)

Sounds interesting and very reasonably priced. I hope that it is sealed. My Sigma 20mm f1.8 is not, but optically the Sigma is much better than I expected (see the DXO review). I look forward to reviews on the Nikon version to see how it is optically.

In reply to:

Paul Liukas: Sigma is for DX only

If you are referring to the Sigma 20mm f1.8, you're mistaken. The Sigma 20, 24 and 28mm f1.8 lenses are all FX.
If you are referring to the Sigma 18-35mm, it is DX only (pity).

On Sigma announces two 150-600mm F/5-6.3 DG OS HSM zooms article (136 comments in total)

I am most intrigued by the hidden bonus announcement of new tele-converters. Sigma makes several lenses which will benefit from these such as the 150mm f2.8 OS macro and the 120-300mmm f2.8 OS sport to name but two.

As for the 150-600mm... good luck competing with the excellent and low cost Tamron. The Tamron is sealed, excellent optically, very fast focusins but probably still lower cost than Sigma will hit on the un-sealed version. Naturally I hope I'm wrong since competition is good and consumers are always the winner in that scenario. Except of course for the confusion Sigma is going to cause with two identical seeming (to many) lenses.

h2k: Wonderful - a super-wide WITH stabilization. And it's really useful to have, despite what others might say.

Both video and hand held stills shooting benefits from stabilization. A tripod is better, but not always practical or even possible; and you don't need 30 sec exposure to get image shake at 30mm.

Direct link | Posted on Sep 12, 2014 at 16:06 UTC

I was very interested in this lens until I noted that they make no mention of of it being sealed. Meaning it almost certainly is not.

So I guess it seems a very interesting lens for those who shoot exclusively indoors in dust-free environments.

In reply to:

eiguoc: I've had the FZ100 for about a week now, still learning. I have problems with playing video's back, they will play with the photofunstudio, but will not play in windows media player. Mine were jerky at the start but changed it to AVCHD & a smaller size. Is there another player that has to be used?

VLC player is free and has all the codecs built in.
To fiddle with the video (such as change the encoding) Handbrake is also free and very capable.

On Accessory Review: Drobo Mini RAID article (149 comments in total)
In reply to:

Michael Fryd: Actually "Dual Drive Redundancy" means the Drobo has the equivalent of three copies of every file. Two drives can fail without you losing data.

The blinking yellow lights means that you are down a drive, and currently have less than the requested level of redundancy. The Drobo is redistributing your data in order to regain the requested redundancy. Once the lights stop blinking, the data has been redistributed, and you can safely lose another drive (unless you have more data than will fit on the remaining drives)

Had you left your Drobo in the typical single drive redundant mode, you would not have lost data when a drive failed. The Drobo would have been faster at redistributing data after the failure, and you would have more available space.

No it doesn't. There are two copies.
data spans a 500gb and a 750gb (called a raid zero). This data is mirrored on another raid 0. Together this is called a raid 10. The way 2 disks can die and not lose data is if two disks from the same raid-1 set die, or one disk from each set dies but they are not mirrors... meaning the 500gb from the first raid and the 750gb from the second raid . If both 500gb's or both 750gbs die all is lost.
The actual layout might be two mirrors which are spanned but the result it is the same.
At no point and in no configuration are there 3 copies of a file

Interesting write up. Nicely done. This is a topic which gets flogged to death in the forums (typically with more passion than facts); it will be nice to have a well written article to refer to.

On Panasonic Lumix DMC-FZ1000 First Impressions Review preview (1282 comments in total)

the big things to me are:
Panasonic = Not weather sealed
Sony = weather sealed

Sony for most of the range needs about 1/2 the light to produce the same exposure settings. It is close to 1 stop faster at most focal lengths.

They both stink at battery life but the Panasonic stinks more (320 v 420 cipa shots)

The sony lens is a little wider, the Panasonic is longer. But the Panasonic over all range of 71.5 to 5.2 vs 73.7 to 10.3 (angle of view) is better.

The real difference maker is likely to be the price. 1300 vs 900 because while the Sony is clearly the better camera is it worth 400 more? Not to most people.

On Sony SLT-A77 II First Impressions Review preview (671 comments in total)
In reply to:

Vitruvius: Top of page 4 - the SLT mirror does NOT redirect 1/3 of the light. It is about 1/3 of a stop of light.

Interesting that they would NOT have included the on-sensor phase detect AF from the a6000 in this camera in addition to the SLT AF sensors. I have about 7000+ actuation shooting action with my A77 and the AF tracking is actually very poor even with fast lenses and SSM / HSM.The only reason I would have spent an extra $400 on the new A77ii was for the same AF system as the a6000. I wonder why they would not have included this on the A77ii? If it is the same sensor why can't they combine the information from both AF systems? But I guess we will have to see how they compare.

1 stop = halving or doubling the light. So 1/3 stop would be 1/6th of the available light.

Direct link | Posted on May 15, 2014 at 19:43 UTC

Except for battery life it seems to be a well specified camera. But given Sony's recent support for a different mount it is a little confusing to see a camera maker competing with itself with two incompatible mounts.

In reply to:

beavertown: 900 buck for this cheap crap???

digifan, you forgot the equivalent aperture won't be as good on the M4/3 and it will only go to 300mm (equiv)... So you're comparing a 27-450 f5.6-10 to a 28-300 f8-f11
Also as I recall the 14-150 isn't that great optically.
I'm sure this Nikon super-zo0m won't be much better. I wouldn't want either one.

In reply to:

raztec: Way to go Nikon. Keep sinking to the bottom of the consumer barrel. While Sigma puts out a constant f1.8 18-35mm zoom you keep sinking lower and lower into the depths of hyperzoom despair. Soon you will be the laughing stock of all photography.

Not exacttly ebsilon. This lens is f6.3 not f5.6 at the long end. Not that it matters these super-zoom lenses are not exactly built with image quality in mind.

Direct link | Posted on Apr 10, 2014 at 15:08 UTC

The bigger issue then what % you get is how MUCH you get. Meaning 15% of a billion is more the 50% of a million. 500px has not be a major player in selling photos. What new marketing efforts are they putting out other then this attempt to get photographers excited about 30% of what thus far has been a rather small number.
Getty (for example) might take a big huge cut but they also tend to sell alot of photos.

How is this the first weather resistant superzoom? The Sony Cyber-shot DSC-RX10 has been out for 4 months and is also sealed.

Yes this was taken with a 20mm (and cropped down a bit). I managed to creep almost right up to it. I took the photo right as it noticed me and spun around.

Correction needed:
On the Sigma 120-300 you say
"... but it's not weatherproofed..."
Problem is, it is weather sealed, the older model with out OS is not weather sealed.
